What it checks
Runs and win rates by character and ascension, streaks, rolling 20-run improvement, deaths, card offers, skips, relics, paths and records. Public field reference. Every rate includes its sample size.
How we know it’s private
The reader runs in a Web Worker in your browser. It loads before file selection and works with Wi-Fi off once this page has loaded. Saves are read-only. The report counts requests after selection and lists each origin and path if any occur.
Limits
Partial coverage. Unsupported fields stay unknown. Boss-entry HP, removals and rest-site choices are Unknown. Only recorded final decks enter card win-rate comparisons. Streaks require dated outcomes for every matching run.
Sources and method
Built by Kingy with AI coding agents and checked against synthetic fixtures. Real-save checks are pending.
